摘要
针对变风量空调系统调适阶段存在的经济性差、最优性未知的现象,以某办公建筑为例,选用实际的复杂系统,利用Modelica机电平台进行仿真,反映系统真实物理特性的系统的热力、水力和控制特性,实现全工况的设计辅助,得到在保障房间温度的前提下减少能耗的最优值。仿真支撑调适的方法可以有效支撑静压控制点的选取和设定的现场调适工作。
Considering the phenomenon of poor economy and unknown optimality of VAV air conditioning system in the commissioning stage,taking an office building as an example,the coupling simulation of thermal,hydraulic and control characteristics of the system reflecting the real physical characteristics of the system is carried out by Modelica electromechanical simulation platform.Finally,the design assistance of the whole working condition is realized,and the optimal setting value of energy saving is obtained under the condition of keeping the room temperature.The simulation supported commissioning method can be used to effectively support the selection and setting of static pressure control points.
